Description

Technical Field

[0001] This utility model relates to the technical field of steel box girder flange plate casting, and in particular to a triangular support for the concrete construction of steel-concrete composite beam flange plate. Background Technology

[0002] The steel box girder requires the use of flange plate formwork on both sides for cast-in-place construction. During construction, the formwork needs to be fixed to the sides of the steel box girder and then disassembled after the flange plate is poured. The formwork installation requires the use of ground supports for support. The ground supports are fixed in designated positions, and then the flange plate formwork is fixed to the top of the ground supports using bolts or other methods to facilitate the subsequent flange plate pouring.

[0003] In some cases, after the steel box girder is installed, its sides are high off the ground, and there are road surfaces or civil facilities at the locations where ground supports need to be set up. In such cases, it is difficult to support the location with ground supports, which can easily affect the work of pouring the flange plate. Utility Model Content

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. The triangular bracket for concrete construction of the flange plate of the steel-concrete composite beam can be directly fixed to the upper and lower insert plates on the web of the steel box girder during installation, thus eliminating the need for ground support, reducing interference with traffic, lowering installation costs, and enabling quick fixing of the triangular bracket to the upper and lower insert plates, improving installation efficiency and ensuring construction safety.

[0015] 2. This is a triangular support for the concrete construction of the flange plate of a steel-concrete composite beam. The channel steel rods are fixed to the bottom of the corresponding channel steel columns. The channel steel rods are inclined and a supporting steel column is connected between the two channel steel columns. The bottom end of the supporting steel column is connected between the two channel steel rods, so that the channel steel rods, channel steel columns and supporting steel columns cooperate to form a triangle. By utilizing the stability characteristics of triangles, the flange plate formwork is supported, ensuring the stability of the flange plate formwork during pouring.

[0016] 3. This triangular bracket for concrete construction of the flange plate of a steel-concrete composite beam has two positioning steel plates welded to the top and bottom sides of two channel steel columns.

During this process, the edge of the upper insert plate will press against the inclined position of the end of the card plate, thereby pressing the card plate to move away from the groove. As the upper steel plate moves into the upper insert plate, when the card plate reaches the slot, the opening and closing part will pull the card plate, and the inclined protrusion at the end of the card plate will be inserted into the slot, thereby completing the initial constraint of the triangular bracket.

[0018] 5. A triangular bracket for concrete construction of the flange plate of a steel-concrete composite beam, wherein two trapezoidal blocks are respectively connected to the top side of the corresponding sliding plate. When disassembly is required, the drive stud is rotated, and the drive stud will move downward, thereby squeezing the two trapezoidal blocks. The two trapezoidal blocks are right-angled trapezoids, and the inclined surfaces of the two trapezoidal blocks are in contact with the drive stud. Therefore, when the drive stud moves downward, it will squeeze the trapezoidal blocks, causing the trapezoidal blocks to move towards the corresponding clamping plate, thereby driving the sliding plate to move towards the corresponding clamping plate, causing the first spring to be compressed and the second spring to be stretched. The compression of the first spring will cause the other end to push the clamping plate, thereby causing the end of the clamping plate to disengage from the corresponding clamping groove, thus completing the disassembly.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figures 1-2 This utility model discloses a triangular support for concrete construction of the flange plate of a steel-concrete composite beam, including a connecting steel plate 1 and a steel box girder web 2. A base insertion tube 31 is connected to one side of the connecting steel plate 1. Two channel steel columns 3 are connected to the side of the connecting steel plate 1. Channel steel rods 4 are connected to the bottom of the two channel steel columns 3. Connecting parts 5 are provided between the channel steel columns 3 and the channel steel rods 4 and the steel box girder web 2. Two supporting parts 6 are also provided between the two channel steel columns 3.

[0027] The connecting member 5 includes an upper steel plate 7, a lower steel plate 8, an upper insert plate 9, and a lower insert plate 10. The upper steel plate 7 is fixedly connected between the ends of the two channel steel columns 3, and the lower steel plate 8 is fixedly connected between the ends of the two channel steel rods 4. The upper insert plate 9 and the lower insert plate 10 are both fixedly connected to the side of the web plate 2 of the steel box girder. The upper steel plate 7 and the upper insert plate 9 are provided with a first screw hole 11, and the lower steel plate 8 and the lower insert plate 10 are provided with a second screw hole 12. A limiting member 13 is connected to the side of the upper steel plate 7 away from the upper insert plate 9.

[0028] In this embodiment, reference Figure 1The connecting steel plate 1 is used to install two channel steel columns 3. The two channel steel columns 3 are welded to the connecting steel plate 1. Then, two corresponding channel steel rods 4 are welded to the bottom sides of the two channel steel columns 3 respectively. Support members 6 are connected to the ends of the channel steel rods 4 and the channel steel columns 3. (Refer to...) Figure 2 The upper steel plate 7 of the channel steel column 3 is welded between the ends of the two channel steel columns 3, and the lower steel plate 8 is welded between the ends of the two channel steel rods 4. The upper steel plate 7 and the lower steel plate 8 are respectively provided with a first screw hole 11 and a second screw hole 12. The upper steel plate 7 and the lower steel plate 8 are respectively inserted into the upper insert plate 9 and the lower insert plate 10, and then fixed with bolts. When the upper steel plate 7 is inserted into the upper insert plate 9, it is initially fixed by the limiting member 13, so that there is no need to hold the triangular bracket by hand, thus improving the efficiency of bolt fixing.

[0029] refer to Figure 2 After the connecting piece 5 is fixed, the steel column 3 is supported by the support piece 6. The triangular bracket is connected to the web plate 2 of the steel box girder to form a support structure, which supports the formwork of the flange plate, so that concrete can be poured into the flange plate formwork to form a complete flange plate. After the concrete is poured and shaped, the triangular bracket can be directly disassembled. The triangular bracket can be quickly disassembled by turning the bolts, which improves the efficiency of disassembly and assembly.

[0030] In addition, a base insertion tube 31 is connected to one side of the connecting steel plate 1. The base insertion tube 31 is used to insert the bottom end of the guardrail into the base insertion tube 31 when the guardrail is installed, so as to protect the workers installing the triangular bracket and ensure their safety.

[0031] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the channel steel rod 4 is inclined on the bottom side of the channel steel column 3 and tilts downward towards the web plate 2 of the steel box girder. Two supporting steel columns 14 are connected between the two channel steel columns 3. The bottom end of the supporting steel column 14 extends between the two channel steel rods 4 and is fixedly connected to the channel steel rod 4.

[0032] In this embodiment, reference Figure 2 The channel steel rod 4 is fixed to the bottom of the corresponding channel steel column 3. The channel steel rod 4 is inclined and a supporting steel column 14 is connected between the two channel steel columns 3. The bottom end of the supporting steel column 14 is connected between the two channel steel rods 4, so that the channel steel rod 4, the channel steel column 3 and the supporting steel column 14 cooperate to form a triangle. Utilizing the stability characteristics of the triangle, the flange plate formwork is supported, ensuring the stability of the flange plate formwork during pouring.

[0033] In a further preferred embodiment of this utility model, such as Figure 2As shown, the support member 6 includes two positioning steel plates 15, which are respectively fixedly connected to the bottom side wall of the channel steel column 3. A screw 16 is provided on the top side of the channel steel column 3. The bottom end of the screw 16 passes through the two positioning steel plates 15 and is slidably connected to the positioning steel plates 15. A nut 17 is rotatably connected to the top side of the upper positioning steel plate 15. The nut 17 is threadedly connected to the screw 16. A positioning tube seat 18 is connected to the top end of the screw 16.

[0034] In this embodiment, reference Figure 2 The support member 6 has two positioning steel plates 15 welded to the top and bottom sides of the two channel steel columns 3, so that when the screw 16 is threaded onto the corresponding two positioning steel plates 15, it avoids shaking. In addition, the rotatable nut 17 can drive the screw 16 to move up and down when the nut 17 rotates, so that the positioning tube seat 18 can fit against the bottom steel pipe of the flange plate template, thereby supporting the flange plate template.

[0035] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the limiting member 13 includes a limiting part and an opening and closing part. The limiting part includes a rectangular post 19, which is fixedly connected to the side of the upper steel plate 7 away from the upper insert plate 9. The two opposite sides of the rectangular post 19 are provided with grooves 20. A retaining plate 21 is slidably connected in the grooves 20. The side of the upper insert plate 9 is provided with a slot 22 corresponding to the retaining plate 21. The end of the retaining plate 21 is inclined.

[0036] In this embodiment, reference Figure 3 The rectangular column 19 has grooves 20 on its two opposite sides, and a retaining plate 21 is slidably connected within the grooves 20. A slot 22 corresponding to the retaining plate 21 is formed on the upper insert plate 9. When installing the triangular bracket, the upper steel plate 7 is inserted into the upper insert plate 9. During this process, the edge of the upper insert plate 9 will press against the inclined end of the retaining plate 21, thereby pressing the retaining plate 21 to move away from the groove 20. As the upper steel plate 7 moves into the upper insert plate 9, when the retaining plate 21 reaches the slot 22, the opening and closing part will pull the retaining plate 21, and the inclined protrusion at the end of the retaining plate 21 will be inserted into the slot 22, thus completing the initial constraint of the triangular bracket.

[0037] In a further preferred embodiment of this utility model, such as Figure 3As shown, the opening and closing part includes an inner groove 23, which is opened inside the rectangular column 19. The inner groove 23 has circular grooves 24 on the two side walls near the two clamping plates 21. Two sliding plates 25 are slidably connected inside the inner groove 23. A first spring 26 is connected between the corresponding sliding plate 25 and the clamping plate 21, and a second spring 27 is connected between the two sliding plates 25. A control element 28 is provided on the top of the inner groove 23.

[0038] In this embodiment, reference Figure 3 In the rectangular column 19, the opening and closing part has an inner groove 23. Two sliding plates 25 are slidably connected in the inner groove 23. The two sliding plates 25 are connected to the two locking plates 21 by a first spring 26. The circular groove 24 is used to avoid the first spring 26. The two sliding plates 25 are connected by a second spring 27. When the two locking plates 21 are squeezed by the side edge of the upper insert plate 9, they will slide in the corresponding groove 20, which will pull the corresponding first spring 26. The first spring 26 will be stretched. When the end of the locking plate 21 reaches the locking groove 22, the locking plate 21 will be pulled back by the first spring 26, so that the end of the locking plate 21 is inserted into the corresponding locking groove 22. At this time, the triangular bracket has completed the initial limitation. When fixing with bolts, there is no need to hold the triangular bracket by hand, and the triangular bracket can be quickly fixed with bolts.

[0039] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the control component 28 includes two trapezoidal blocks 29, which are respectively fixedly connected to the top sides of the two slide plates 25. The top side of the rectangular column 19 is threadedly connected to a drive stud 30. The bottom end of the drive stud 30 is inserted into the inner groove 23 and located between the two trapezoidal blocks 29. The bottom end of the drive stud 30 is in contact with the two trapezoidal blocks 29.

[0040] In this embodiment, reference Figure 3 The trapezoidal blocks are connected to the top side of the corresponding slide plate 25. When disassembly is required, the drive stud 30 is rotated and moved downward, thereby squeezing the two trapezoidal blocks. The two trapezoidal blocks are right-angled trapezoids, and the inclined surfaces of the two trapezoidal blocks are in contact with the drive stud 30. Therefore, when the drive stud 30 moves downward, it will squeeze the trapezoidal blocks, causing the trapezoidal blocks 29 to move towards the corresponding clamping plate 21, thereby driving the slide plate 25 to move towards the corresponding clamping plate 21. This causes the first spring 26 to be compressed and the second spring 27 to be stretched. The compression of the first spring 26 will cause the other end to push the clamping plate 21, thereby causing the end of the clamping plate 21 to disengage from the corresponding slot 22, thus completing the disassembly.

[0041] After disassembly, rotate the drive stud 30. The drive stud 30 moves upward. When the drive stud 30 moves upward, the squeezing force on the two trapezoidal blocks 29 gradually decreases, and the stretching force on the second spring 27 gradually decreases, causing it to retract. This, in turn, pulls the two first springs 26 back to their original positions. The retraction of the first springs 26 will pull the card plate 21 back to its original position for subsequent reuse.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
